Due to DME’s physical and chemical properties, (it can be liquefied at low pressures, 5 bars), it has been established as a diesel substitute.
The emission – related benefits of DME as shown by Volvo Trucks certainly point to zero particulates, lower NOx and 10% lower CO2 emissions but with equivalent fuel efficiency against a diesel engine.
The storage, handling, distribution and safety aspects of DME are very similar to those of LPG. JIS standard K2180, ISO 16861:2015 and ASTM D7901 - 14b are relevant standards for DME.

Mack Trucks has begun a demonstration to test the performance of a Dimethyl Ether (DME)-powered Mack Pinnacle model.
“We believe DME shows great promise, and we are pleased to be working with our longtime customer DSNY to evaluate the fuel as a viable alternative to diesel.” said Dennis Slagle, president of Mack Trucks.
DME delivers the same exceptional performance as diesel fuel and generates no soot.
The fuel offers many benefits, including that it can be made from multiple sustainable feedstocks, such as food waste, animal waste, grass clippings and natural gas. It offers the same performance and energy efficiency as diesel.
DME does not require cryogenic temperatures or high tank pressures.
